public IndexableField createField(SchemaField field, Object value, float boost)
FieldType
By default, the indexed value is the same as the stored value (taken from toInternal()). Having a different representation for external, internal, and indexed would present quite a few problems given the current Lucene architecture. An analyzer for adding docs would need to translate internal->indexed while an analyzer for querying would need to translate external->indexed.
The only other alternative to having internal==indexed would be to have internal==external. In this case, toInternal should convert to the indexed representation, toExternal() should do nothing, and createField() should *not* call toInternal, but use the external value and set tokenized=true to get Lucene to convert to the internal(indexed) form.
:TODO: clean up and clarify this explanation.
